Hi friends, sorry for my english.
I searched many sites but could not find.
What are the meanings of the fuses set in the bootloader loaded atmega328?
program can be pulled from the bootloader 328 installed? (downloadable)?
Or..................
328 bootloader installed program can be pulled (downloadable)?
thanks for the answers
do I have a friend who knows _?
The descriptions of what the fuses do are in the datasheet - they set things that need to be set before any code runs - the clock source, BOD (brown-out detect) configuration, and a few other things.
The lockbits determine whether you can read out the sketch binary; on the official boards they are set to permit this (this is required since the IDE verifies the sketch after upload). So you can read out the binary and get the .hex file.
Note that it is not possible to regenerate the sketch source code from the .hex file (the .hex file is the compiled binary - it is to arduino sketches what the executable is for an application for a computer; you can't get the source code back). The source code contains information that is not present in the .hex file (a lot of it, actually). Unless you can read AVR machine code, all you can do with the .hex file is copy the sketch to another arduino with the same processor.
Drazzy thank you very much for your reply .
I have one more question.
Can I turn off fuses for importing hexx file via IDE _??
how can I do it _?
